Serial No. 340,480.

This invention relates to electric suction cleaners and has for itsobject the provision of an improved electrical connection. and switchadapted to facilitate the removal and replacement of the electric cordand/or hanlfile and the actuation of the switch by the oot.

Fig. 1 is a side elevation of a specimen cleaner embodying myimprovements; Fig.

1c 2 is a perspective view of the electrical switch and connection,showing the parts separated; and Fig. 3 is a sectional View of theswitch and connector.

The cleaner herein shown is of the well 1.; known horizontal typecomprising a collecting nozzle 1, fan casing 2 and motor housing 3,rigidly secured together in the order named from front to rear thenozzle having an inlet mouth a and the casing having wheels 5, 5 bywhich it is supported with said mouth in operative relation to thesupporting surface. Communicating with'one side of the fan casing is theoutlet neck 6 to which is secured a dust bag (not shown);

2:] and pivoted to the casing as by the lugs 7 is ahandle yoke 8 towhich is secured a handle 9 by which the cleaner is manipulated.0rdinarily the electric current is conveyed to the motor (not shown)enclosed within the housing 3, by means of a flexible conductor 10sometimes fastened to the handle; and it is sometimes convenient todisconnect the cord from the casing, either to enable the removal of thehandle from the cleaner when 3.; the cord is attached to said handle asit sometimes is, or for other reasons.

To accomplish this, and also to facilitate the operation of thecontrolling switch, l have provided the fittin shown in Figs. 1

4 and 2 which comprises a ollow, metal housing 12 formed at one sidewith flanges 13 by which it is screwed to the hou'smg, and formed at itsopposite side with a .slot 14:, through which projects a lever 15,adapted to be actuated by the users foot.

ing is formed at one endfnamely the end presented toward the rear of thecleaner with a hollow extension 16, forming a shield for the fingers 17of a separable electric connection. The other member of said connec-Said castion comprises a plug 18, generally made of insulating materialcarried by the end of the conductor 10, and having sockets 19 thereinfor the reception of the fingers 17, and contact members in said socketssuitably connected to conductors in the chord 10. Suitable switchmechanism (not shown) located inside the housing 12 serves to make andbreak the circuit between the fingers 17 and v the motor depending uponthe position of the lever 15.

I do not consider it necessary to illustrate this switch mechanism, orto describe it at any length, since the same is not my invention, butseveral constructions susceptible of being used herein are known, andare in sale inthe market, and available and known to those skilled inthe art.

Having thus described my invention what I claim is:

l. A combined switch and separable connector for electrip vacuumcleaners comprising a hollow housing having at one side an attachingflange, at the opposite side an opening, and between them a hollowprojecting neck having parallel walls, switch mechanism inside saidhousing and having-a pair of terminals projecting into said neck andparallel thereto; a plug fitting removably in said neck and havingcontact members cooperating with said terminals, and an operating memberfor said switch projecting through said opening and positioned to bemoved by the operators foot.

2. An electric floor cleaning device comprising a casing movably'supported close to the floor, said casing having a switch casing formedwith a vertical slot, a lever projecting from said slot and movable upand down therein, and switch mechanism connected to said lever to beoperated thereby, said lever being positioned close to the floor and atone side of the device where it can be reachedby the operators foot andthe entire upper face of said lever having a downward slope.

3. An electric floor cleaning device comprising a casing having a fanchamber and a motor housing arranged in the order named from front torear, the motor housing having a substantially cylindrical externalpart, and 1 wheels whereby said casing is supported with said housingsubstantially horizontal and near the floor, of a vertically movablecontrolling lever projecting outwardly and downwardly from said housingat one side and, the upper face of said lever having an outward anddownward slope in at least its depressed position.

4:. An electric floor cleaner comprising a famchamber and a motorhousing secured together andwheels supporting said casing with saidmotor housing substantially horizontal and at the rear of thefan-chamber, and a combined switch and connector carried by said housingand comprising a hollow casing secured to said housing in the rear ofsaid fan-chamber, said casing having a vertical slot in its side whichis opposite said housing and an opening in a side which is adjacent tosaid housing, a separable connector having part inside said casing and acompanion part removably received in said opening, and a switch in saidcasing having an operating lever projecting outwardly and downwardlythrough said slot.

In testimony whereof I hereunto afix my signature.
